MAS FLAG Epoxy Resin

MAS FLAG resin is a medium body epoxy specifically designed to be used as an adhesive and structural laminating foundation. It's thicker formula resists sagging in vertical applications. Medium viscosity works well with fillers when fairing putties, gluing slurries and filleting systems are required.

When mixed with medium hardener, FLAG is more reactive than low viscosity MAS resin. This keeps fillets and fairing compounds from slumping. FLAG resin can be sanded the next day when cured at 60 degrees F or warmer with Medium Hardener. Use with all MAS hardeners. Note: For filled applications, we recommend using MAS Medium Hardener.

We highly recommend this resin for general purpose gluing applications where wet-out of fiberglass is not a consideration, and for filleting and fairing.

2012-07-02WILLIAM RICHARDS asked:Can I use MAS Flag Epoxy to laminate Oak frames in a large wooden boat or is it to hard and not flexible enough., and if so what type of epoxy can I use.?

2012-07-02ALAN BAMBINA:William, yes, you can use MAS epoxy resin to laminate oak frames on your boat. I use it to laminate the fore and aft stems on many cedar strip canoes, and the ash and red oak held its shape and is extremely strong. I see no problems with your intended use. The frames will be flexible enough to withstand the pounding they'll see. Good luck with your project.

2012-07-02STEVE RICHARDT:William, I have not used MAS for laminating yet sorry I can not speak dirrectly to your question. I have been sealing wood projects with it and am very pleased with the clear stable out come. The MAS I have is the medium viscousity. I suggest looking at the thicker product so that the joint is less likely be to dry.
Steve,
Good luck.

will the Anti Skid fiber backing bond to the MAS resin if I use as an adhesive?

2012-04-23AL RITTER:I would think it would, but I have never tried. What I have found is the biggest killer of most stiff materials is the differential in the expansion rates of the two materials. If it is not very close on expansion rate please use a flex type adhesive.

2012-04-24ALLISON PASCHKE:Epoxy resin is not a great adhesive for shiny smooth things (it will work fine for a while but will become brittle and separate after a while) but works great for porous and rough surfaces. Also it doesn't hold up in sunlight. If your adhesive will not be visible, I recommend a marine construction adhesive, available in tubes in hardware stores.

2012-04-24ALLISON PASCHKE:Yes, I agree it doesn't flex well.

2012-04-27MIKE GRAY:I love this stuff most user frendly epoxy out there it will bond to allmost any fiberglass surface if thourly cleaned and sanded with 80 grit paper I'm not familuer with the antiskid pads your talking about but if there not made of plastic and the epoxy can soak in to them they should stick but if there rubber or plastic forget about it remember to protect the epoxy from uv rays or it will break down

2013-10-31NATHAN TESLIK:I have used epoxy to bond non-skid additives. Apply the epoxy and sprinkle on the grit. Paint over it. Worked better than any nonskid pad I have seen.

We are redoing the decks on an Alberg 35. There was quite a bit of delamination and water damage. We have cut out bad areas and reglassed. Mas is extremely easy to mix and use. We have used over 5 gal so far.

Very usable odor-free product. Good pot life and strong too. Be careful with the resin pump though -- FLAG resin is thicker, so the pump return stroke is slower. Rushing the pump may reduce the amount of resin in the mix.

This is a great product. We are rebuilding the deck on a Alberg 35. This product has a long working time when mixed with the slow hardner or medium hardner. It has no odor and can actually be cleaned up with white vinegar. It is sandable too.
